Workflow between desktop and mobile apps

I would like to see a tighter workflow between desktop and mobile apps. One possible way of doing this would be allowing projects to go back and forth between, for example photoshop and sketch. Currently I believe you can go only from sketch to photoshop and not back. An other Possibility would be to integrate a way of using the iPad and Apple Pencil as a drawing tablet for photoshop and other apps (similar to how Wacom tablets work) it could be cool to see this done through sketch app. Hope To see this in the future!
